et al.

We present the first search for CPT-violating effects in the mixing of B⁰_s mesons using the full Run II data set with an integrated luminosity of 10.4 fb^-1 of proton-antiproton collisions collected using the D0 detector at the Fermilab Tevatron Collider. We measure the CPT-violating asymmetry in the decay B⁰_s → µ^±D^±_s as a function of celestial direction and sidereal phase. We find no evidence for CPT-violating effects and place limits on the direction and magnitude of flavor-dependent CPTand Lorentz-invariance violating coupling coefficients. We find 95% confidence intervals of Δa⊥ < 1.2 × 10^-12 GeV and (-0.8 < ΔaT - 0.396Δa_Z < 3.9) × 10^-13 GeV.
